To all whom it may concern:

Be it known tiret l, Serene HfSAoER, n citizen of the United States, resident of Rochester, in the county o Monroe and State of New York, have invented certain new enti use ni inprovenients in Bumpers for Automobiles, of which tneoilowing is ers for automobiles, and more pntwuierly to the connection. between snif. bumpers and the vehicle, en object of this intention being to provide for attaching the bumper snpporting arms to tine curved or ellipticei "lent springs which are nsnelljy arranged et the rear of the vehicle,

To this and ether ends, the invention oonsists of ce n ports and combinations of parts eil Wiiien will be hereinafter clescribed, the novei tentures being pointed ont in the nppeneeu In the drawn Figure l n Vertical section through n lnnnper supporting erin attached to n leef spring;

At the present time it is customary to eniployl eybnnipor comprising n bumper bnr which, in this instzrnce, is a member i nrrnnged et tire front or the rear of the vehicle und supported oy e pair of supporting arms. Those supporting arnis may be of any suitable constrncticn, but in this instence eeen embodies en 4enter member 2 secured at its outer end to 'the bumper ber, en inner niember 3 on which tire outer member is guided for longitudinal movement, and :i spring; e., or other resiiient device, interposed.

'the inner member 3 has a block 5 :uljustnbly seeure at its inner end anti in the forxnot e segment nl s circle with a face 6 for engaging the portion oi2 the vehicle on which the bumper supporting erin is errnnged. The inner member 3 is adjustable on the curved' fece Y of the block, so as to i Y. Trie m'esent in/entren re s to trampn plan View of erin; end e sectional View on the iine 3-3,
